Please help me with the programming I’m stressed out with this question all day

Question

1.00/5 (1 vote)

See more:

Implement a parser for the programming language myC– in Project one using FLEX and BISON. The parser builds an abstract syntax tree (AST) for the input program and then pretty-prints the AST. Write.
Five programs in myC–. Your programs must collectively use all types of statements. For instance, you may have a myC– program that reads three numbers and printing the maximum of these numbers and another myC– program that prints the sum of integers from 1 to n where n is obtained by an input statement

What I have tried:

I couldn’t even start it I tried to solve it all day. This is a assignment I need to submit it today. This is my first time in this website. Hope I can get a help. Thank you

myC ? never heard of it and can't even find it when Googling, are you sure you spelled that correctly?

Azor Ahai 5-Oct-21 14:03pm

I’m sorry, by myC it means c programming here

Greg Utas 5-Oct-21 13:58pm

This is far from an assignment for a novice, and you left it until the day it's due? You've got a serious problem, not the least of which is that this isn't a site where people do homework for you.

Azor Ahai 5-Oct-21 14:04pm

I didn’t leave it like that. I’ve been tryin to solve this all day. For couple days

Solution 1

Nobody can write this for you, nor should they.

First, you would learn nothing at all, and that's not helping you.

Second, there is no specification for the "myC" language. Without that, you cannot possibly implement a parser, let alone do it in FLEX and BISON.

Solution 3

While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

If you are having problems getting started at all, then this may help: How to Write Code to Solve a Problem, A Beginner's Guide[^]

But to be honest, you have probably left it too late if you have to submit today - you have procrastinated too long I suspect. Take that as a lesson: deadline are important, and time management really does matter.

These solutions presented here, don't even come close in answering the initial
question asked, none of them. It reminds me of my compiler construction class,
where I went to college. To implement a parser, you need to start at square one.
First, write a lexical analyzer, then a symbol table, and then a parser, and then
I believe there are a few more major phases left to build and implement. The
first two steps aren't to bad to write, but the parser phase is a real challange to
write. So the owner of this initial question better get his little caboose running
down the track. You have state/next-state table(s) to construct. Correct syntax
grammer better fit/follow the state/next-state tables. Also, include syntax/grammer
error detection. With making these tables, you are going to be drawing lines all
over the place. That's all my little brain remembers, but it takes times and
patience, and not asking anybody else to do your school work. Parsers are not
built overnight.

So how would you respond to the OP when he asks for "Implement a parser for the programming language ... This is a assignment I need to submit it today"?

Even if we wanted to do his homework for him (and I suspect this assignment was given some months ago) there is no way we could practically do it for him. So unless he has the bulk of the work done - and his question doesn't indicate that at all - there is nothing we can do except tell him to pull his finger out earier next time ...

Azor Ahai 25-Oct-21 7:19am

This alone motivates me to work on my programs more. thank you.i appreciate it.

Member 15028314 6-Oct-21 23:31pm

Okay, OriginalGriff: A teacher would say, have you done anything?? Show me. This is like asking a college professor for an "A", when you have not done anything to warrant a grade of "A". So, if you want it bad enough, better start producing the lexical analyizer, and symbol table setup, and the startings of a new language parser, We/I would think about some help.

OriginalGriff 7-Oct-21 2:09am

What kind of help do you give on a big project that doesn't appear to have been started? :sigh:

Member 15028314 11-Oct-21 0:07am

So OriginalGriff, you ask what help would I give on a big project that hasn't been started? None. No workable effort has been shown. Sigh... What are you baiting me for?? If you have a secure site/place/connection and neutral, I'll show you my big project that I've worked on for so long, and I'll show you some effort. So, if I may say and ask it kindly and gentely, now show or blow. I think this is what you are baiting me for.

OriginalGriff 11-Oct-21 2:10am

Read your original "question" again, from the viewpoint of someone outside the project. What does it look like to you?

Member 15028314 18-Oct-21 1:33am

OOkay OriginalGriff, thee original question(at the top of this page) that
you referenced was about someone who wanted to glory from somebody else's work,
because he/she didn't want to up get off their caboose and put forth the
required effort. He/she is quite lazy! The way you act and interact with people,
whom may not have the knowledge you have, shows that you have a lot to learn
about working with people. As for being from the old college, I've learned
Cobol, Algol, Pascal at college, and Fortran, "C", C# on my own from working
examples and have done quite well in college and on my own. And I've recieved
some good grades for it from a big US university.
And yes, I even have a big C# project too with problems that I can't solve, so I
came here for help. And yet, people come here in all shapes and with limited
knowledge; and maybe they don't know how to fully express the problem(s)
at hand or even understand the answer(s) given. Maybe they even have a
diability issues that you don't even know about that may affect them in some ways,
but they try anyway to achieve success in any way they can. From someone of
the old college, you need to take people for who they are, and don't you dare
look down on them. Weren't you once in a learning state at many times,
wanting to learn/know more, and trying to fix a programming problem or
problems. So now, as was said before, show or blow - in showing a little a
compassion in working with whom needs some help, and not act like someone
whom is almighty at the keyboard. If you "blow", I feel quite sorry for you.
But if you 'show', you have a lot of potential, cause you have a lot to learn
about people, and can have success in other ways of helping.

ROFL.

Azor Ahai 25-Oct-21 7:25am

for someone who shifted from business major to programming, everything is quite vague for me to take. i know i shouldnt have just asked anyone to solve my problem without even getting started with it myself. its not like i dont work hard on it, sometimes i get stuck for hours on a some problem. thus tried to seek an answer. sorry about that guys. i will provide the work i have done next time before asking a specific question.

Richard MacCutchan 25-Oct-21 7:31am

You need to understand that this site is not here to do other people's work for them; especially school and college assignments. And unless you provide specific details of what you have done and where it is failing it is impossible for anyone to give any useful advice.

But ny comment was really aimed at the person who posted the message above, rather than at you.

Member 15028314 25-Oct-21 11:30am

To Richard MacCutchan: OK Richard, we need to set the record straight on a few points...

1) I have been out of college for about 36 years.
2) While in college, I was a computer science major(not a business major) and I graduated with a B.S. degree.
So are you,
A) a flunky,
B) Do you have an AAS, or a B.S. or better?
C) You choose.
3) And definitely, this is not a school project. It came from ideas I learned from out in industry.
More over, where do you get off playing god on/from a distant keyboard - claiming you are better
than other people/person, and that you know all!
I have been working on this project for a long time. It went from being VB/"C"/DLL project to
C#/"C"/DLL project.
4) I write for no one else!.
5) You sure do read between the lines, making a lot of a false assumptions.
6) Just to add a little understanding to that little frame of mind, I learned C# from examples, working
at that. I do not claim to know C# like I should. But thru using working C# examples and trying
different things out, I've done a lot on my project, and it has come a long ways.
7) So don't come across as an all-knowing individual, claiming you know all the information neccesary to
make a snap decision - which usually is false.

This all started when I stated some correct and true facts about someone who wanted a new language parser
built Yet he/she had not stated nor shown nor indicated any initial work or even provided some effort
had been provided. And I directly said, that individual was lazy and the he/she should get off their little
caboose and start working.

Is taking the truth to hard to take or swallow? So my two-bits worth to Richard MacCutchan is to get up off
your lazy caboose and learn the facts first and stop making a lot of a false assumptions - thinking that you are
all knowing and high and mighty - of which you are NOT! I hate being put down and being belittled.
KNOW the facts first. ALL I want is some help, Please...

As in a western movie, one gunfighter is calling you out. I want to know if you are going to SHOW or BLOW?.
